There are lots of ways that you can cut your energy bills. Small things like loft insulation and insulated glass windows can amount to real savings over the course of the year. I was reading about
double pane glass the other day called Heat Mirror Insulating glass. What it does is combine two air spaces to help block heat flow and provide higher insulation than ordinary glass. This helps cut down on emissions and helps reduce heating and cooling loads, saving energy. It also helps to block around 99% of the suns UV radiation so can help prevent furniture from fading and sun damage.
